2 Claims. (Cl. .29969) The present invention relates to new and usefulimprovements in lawn sprinkler Thev primary object of the inven ion isto provide a sprinkler best adapted for use in spraying lawns that canbe readily moved from place t place, as desired; and which is adjustablevertidecreasing the distribution `of water therefrom. Y

Another object of the invention is to provide a lawn sprinkler includinga sprinkler head which will be operated or rotated by the force of thewater, said sprinkler head being mounted in suitare practicallyunexpcsed to the ow of water through the sprinkler head.

The invention also consists in certain other features of constructionand in the combination several parts, to be hereinafter fullydescribed,illustrated in the accompanying drawings and specifically pointed out inthe appended claims.

In describing my invention in detail, reference I will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

, Figure 1 is a side elevational view of alawn sprinkler. embodying thefeatureso the present invention.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view Figure 1.

ent invention, a means has been provided for taken subf Figure 4v is ahorizontal sectional view takenl substantially on the line 4 4 of Figue.I

Figure 5 is a detailed sectional view of the lower end of the sprinklerillustrating the connecf tion with the nozzle of a hose. Figure 6 isadetailed sectional view of one 0 the sprinkler arms taken substantiallyon the line 6-6 of Figure 1.

Referring to the drawings for a more detailed -description thereof, theimproved numeral is supported on legs 'Il which are secured to the tubel0', a's indicated I2, the opposed ends of which are connected, asindicated at I3, -to a. coupling' Il mounted onthe lower end of the tubeIl. The legs Il present substantially 'the shape of a tripod and aremoved over a lawn. as desired. 'Y As I have indicated, the tubularsection 9. telescopes,within'the section Ill and isreadily extensiblefor increasing r decreasing the height 'of the sprinkler. In accordancewith the presvided with exteriorly the tubel l n on the supported aleather,

rectly above the washer Awasher I8 and packing I9 will provide lockingthe upper section 9 in its adjusted position and referring moreparticularly to Figure 3 of the drawings, it will be observed that thelower end of the tube 9 flares outwardly, as indicated at I5, forcontactual engagement with the wall of the interior of the tube I0.'I'he upper end of the tube Il! is provided with exteriorly formedthreads I6 which-receive a cap nut I1, said nut adapted to lock the tube9 in its adjusted position, as will hereinafter appear. The upper end ofinterior thereof is formed with indicated at I8, on which is or thelike, washer I9. Di- I9 is positioned a exible packing member 20 whichis retained in place by means of the cap nut l1. When desiring to raiseor within the tubular member I0 the packing nut I1 is rst released andthe'tubular member ,"9 moved to its desired position. frightening thepacking nutywill then securely retain thetubular member 9 in its adustedposition. Use of the a water a convexed seat, as

tight connection within the cap nut l1. The sprinkler reference numeral2l is rotatably mounted -on the upper end o'i the tubular member 9. The

upper end of the tubular member 9 is provided with exterlorly formedthreads 22 which receive 23, the latter being also pro- I an extensioncollar formed threads 24. Adjustment of the head 2l is accomplished byloosening or tightening the extension collar 23. A diskshaped washer 25is held on the upper end of the collar 23, said' washer being formedwith a censprinkler which at 4t from water,

tire assembly including be readily tral opening 28 which communicateswith the Pipe 21. The lower outwardly, as indicated at 28, and restsupon the washer 25, said pipe revolving within roller bearings 29. 'Arelatively thin metal retaining member 30 surrounds the pipe v21 and isdisposed'over the roller bearings 29 for protecting the same dirt, dust,and the like, and the enthe roller bearings 29 held in position by meanssaid nuty beingl interiorly and retainer 30 are of the cap nut 3l,

Athreadedvifory engagement with the threads 2l of the collar 23. By thisconstruction the discharge 9 and I0 and into of water through thesections attached therethe pipe`21 and its sprinkler arms tofwill causethe pipe 21 to rotate retaining' memberl 3l will protect the bearingslower the tubular member 9 Y head-generally deposited by the end ofthepipe 24 is flanged within theu bearings 22.* -Provision of the washer.25 and,

' upwardly through the sections 9,v

` per end of the pipe 21 is formed with an angular which extendsupwardly and section of tubing 34 laterally therefrom, said sectionbeing also formed with a series of openings through which water isdischarged. The action of 21 and outwardly through the arms 32 willeffect a rotary motion to the entire head 2| in a manner well known inthe art, and as I have indicated Water will also be discharged throughthe end of the section 34 which will be revolving with the pipe 21. Theconstruction of the head 2| is such that the leakage of water issubstantially precluded.

The sprinkler s is adapted to be connected with.'

a water outlet through a section of hose 35, such as is shown in Figure1 of the drawings. For attaching the hose to the sprinkler, the lowerend of the tubular section I is provided with exteriorly Aformed threads36 by means of which an elbow coupling 31 may be attached thereto. Theend 38 of the hose 35 threadedly engages vthe coupling 31 thusprovidingv a free passage of water from the hose 35.

If desired, the cap nut I1 may be formed with a pair of laterallyextending arms 39 adapted to be engaged for tightening and looseningsaid nut in the adjustment of the sprinkler.

It is thought that the operation and advantages of the sprinkler arereadily apparent from the above description when taken in connectionwith the accompanying drawings.

Also it will be understood, of course, by those skilled in the art thatvariations in the herethe water passing I0 and pipe inabove-describeddevice involving the substitution of substantial equivalents for thedevices described are intended to be comprehended within'.

the spirit of the present invention and that the invention is capable ofextended' application and is not conflnedto the exact showing of thedraw- A ings nor to the precise construction described and, therefore,such changes and modications may be made therein as do not affect thespirit of the invention nor exceed the scope thereof as, expressed inthe appended claims.

What is claimed is:

1. In a lawn sprinkling device, a tubular head of approximatelysemicircular formation 'having the ends closed, the said head having itsend portions depending and provided with a plurality of longitudinallyspaced discharge apertures at one side thereof, a vertically dependingpipe having communicative connection with the center of the said headand adapted for connection with a, supv ply conduit, and an angulardischarge tube pro- Vfeed pipe having -end of the said pipe and jectingupwardly from the center portion ofthe head. I

A 2. In a sprinkling device, a vertically supported tube, a tubularsection slidably mounted in the rst mentioned tube for verticaladjustment, a cap nut mounted on the upwardly projecting end of theadjustable tube section, an upstanding mounted within the cap nut, atubular sprinkler head of approximately4 semicircular curvature havingcommunicative connectionwith the upper having its ends closed anddepending with relation to its center pdrtion, the said depending endportions of the head having a plurality of longitudinally spaced disanda tubular projection having communicative connection with the centerportion of the `head and extending upwardly therefrom..
